No, it's because your Hunspell dictionaries seem to be misconfigured.

This list doesn't include a single .aff file, and Emacs needs that to
initialize the dictionaries properly.

What does Hunspell display if you invoke it from the shell prompt with
the -D switch?

And where did you download this port of Hunspell from?
